Automatic Control Design of Metallurgical Raw Material Preparation Plant
Introduction
A metallurgical raw material preparation plant is the foundation of Metallurgy and plays a very important role in the process of iron and steel production. Its task is to prepare auxiliaries, such as coke, lime, etc., that are necessary raw materials for the production of iron and steel. To ensure the efficiency of iron and steel production, it is necessary to design an automatic control system for the raw material preparation plant to provide the safe, accurate, and efficient operation of the production process.
Description
This automatic control design of the metallurgical raw material preparation plant is based on the latest advanced technology such as Integrated Automation and DCS. The system employs a distributed control model, in which each device is given certain functions and is independently controlled by a local microcomputer. The system itself is divided into two parts, the central monitoring and control unit and the distributed control units.
Central monitoring and control unit. The purpose of the central monitoring and control unit is to supervise the overall performance of the raw material preparation plant. It is responsible for monitoring and controlling the temperature, pressure, flow rate, and other parameters of each device in real time. It is also used to store the operation data of the plant and generate corresponding production reports.
Distributed control units. The distributed control units are responsible for the distributed control of each device in the plant. Each unit is composed of an independent microcomputer, which is responsible for controlling the corresponding device including the start-up, stopping and regulation.
Finally, each device is connected to a communication bus for the transmission of control signals, feedback signals and operation data.
Operation
The operation of the system is divided into two parts, the manual operation and the automatic operation.
Manual operation. In the manual operation mode, the operator manually sets the parameters of each device, such as temperature and pressure, according to the operation requirements. After that, he/she can start or stop the device. The system will accept the operators instructions and control the device according to the settings.
Automatic operation. In the automatic operation mode, the system will automatically set the parameters according to the production requirements. Once the device is started, the system will monitor and control the device in real time to ensure that the parameters are kept within the preset range.
Safety measures
1. The system is designed with multiple redundant functions to ensure that the system is running continuously and stably.
2. The system is equipped with emergency shutdown functions to ensure the safety of the device and operator in emergency situations.
3. The system is also equipped with safety protection devices to prevent the device from being damaged due to abnormal operation.
Conclusion
This design of the automatic control system for the metallurgical raw material preparation plant provides safe, accurate, and efficient operation of the whole process. It ensures the stability and reliability of the system and makes the production process of the raw material preparation plant more convenient and efficient.
